IMFROVEMENT IN CORN-PLANTERS.

Specification forming part of Letters Patent No. 147,392, dated February 10, 1874; application filed November 1, 1873.

To all whom it may concern;

Be it known that I, ROBERT S. HAZEN, Sr., of Oalamus, in the county of Clinton and State of Iowa, have invented an Improved Corn- Planter, of which the following is a specification:

Figure 1 is a plan or top, view of my im- Fig. 2 is a side elevation of the same. Fig. 3 is a vertical longitudinal section of the same, the line 0 0, Fig. 1, indicating the plane of section. Fig. 4 is a vertical transverse section of the same on the line k L, Fig. 1. Fig. 5 is a detail vertical longitudinal section on an enlarged scale, the line 0 k, Fig. 1, indicating the plane of section. Fig. 6 is a detail horizontal section on the line (1 q, Fig. 5; Fig. 7, an enlarged detail sectional view on the same plane as Fig. 3, showin g the manner of fastening the tongue.

Similar letters of reference iinlicate corrcsponding parts in all the figures.

This invention consists, first, in the combination, with the seed-slide, of two lovers, an adjustable pin, and a grooved cam, for the purpose of operating the seed-slide; and, sec ondly, in the combination of a cam, having a spring in its caln'groove, with a hand-lever, ratchet-wheel, adjustable pin, and levers, for the purpose of starting the hills when the wheels are loose upon the axle.

In the accompanying drawing, the letter A represents the frame of the corn-planter. The same is made of wood or other material, of suitable size and shape, and is supported on the ground by two wheels, B B, both of which are hung on an axle, O, which has its bearings in the frame A. Both wheels B B are lengthwise adjustable 011 this axle, and can be moved against clutches l) D, that are firmly attached to the axle, as is more fully indicated in Fig. 4. lVhen both wheels are withdrawn from these clutches, they turn loose on the axle; but when, by means of proper levers E ll, one wheel or the other is brought against its corresponding clutch, such wheel will serve to rotate the axle G. F is the drivers seat, secured upon the frame A in suitable manner. G G are the seed-boxes, arranged in front of the wheels B on the frame A. H is the tongue or pole. This tongue is, with its end, inserted in a socket formed in a cross-bar, a, of the frame A, and rests on another cross-bar, Z), of

when the tongue is in place, is brought to bear against the front edge of a projection or lip, g, of the tongue, as is clearly shown 111 Fig. 7 and in Fig. 3. Thus, by means of latch f, and also by its teeth I), is the tongue firmly held in place and caused to take proper hold of the frame A in drawing the same ahead. Still, although the tongue is so firmly attached, it may be readily removed by merely lifting the latch f, and then raising the teeth (I clear of the cross-bar b. I is the seed-slide, extending laterally across the frame A and under the perforated bottoms of both seedboxes G G. Its ends are perforated to correspond to the apertures in the bottoms of the seed-boxes, and to deposit the quantity of seed received by the slide into the spouts J, that are formed beneath the seed-boxes, as indicated in Fig. 5. \Vhen the slide I is re ciproeated transversely, it causes simultaneous action of both seed-boxes.

Motion is imparted to the slide I by a lever, L, which is, at 71, (see Fig. 1,) pivoted to the frame A, and which, at its front end, connects, by a swivel-joint, with the slide I. At the rear end is pivoted, to the lever L,another lever, M, which connects with a pin, 1', that passes through a longitudinal slot of the lever L. \Vhen the lever M is swung forward into the position shown in Fig. l, to carry the pin i forward, the lower downwardly-proj ecting end of such pin will be withdrawn from contact with the operating-cam that is mounted upon the axle O 5 but when the lever M is swung backward and locked to a projecting arched rack, j, that is formed on the lever L, it will thereby move the pin i backward and cause the lower end of such pin to enter the camgroove of a cam, N, mounted upon the axle 0. As this cam is being revolved by means of the axle it causes the pin i to vibrate in the cam-groove in conformity to the shape of the same, and thereby to oscillate the lever L and operate the slide I.

The cam-groove of the cam N is made with lateral angles, as indicated in Fig. l and also in Figz ei, and has springs l formed as parts of the sides, so that, by such springs, the pin 2', when it arrives at a bend of the groove, will be violently thrown into the next section of such groove, so that thus the motions of the lever L will not be gradual, but sudden shiftings, and the slide I be moved suddenly accord ingly. A lever, O, which has a pawl engaging with a ratchet-wheel, m, on the axle 0, serves,

when used by hand, to impart intermittent ro tary motion to such ratchet-wheel, and thereby also to the cam N and axle G, the ratchet-wheel being mounted upon the axle. This lever is only used, when both wheels B B are loose on the axle O, to start the first hill after the turnin g of the planter at the end of a row, or otherwise, whenever it is found desirable not to move the seed-slide by means of the wheels. \Vhen one of the wheels actuates the axle G, the lever O is thrown and held out of contact with the ratchet-wheel. The spout J under each seedbox G is, by a partition, '11, divided into two compartments longitudinally. Both these compartments can be closed by a T- shaped gate, P, which is pivoted in the spent, as shown in Figs. 5 and 6, and which, by its projecting arm 0, connects with the seed-slide I, so that the seed-slide will vibrate the gate 1, and thereby alternately open one and the other compartment of the spout. Thus, as the seed is, by the slide, taken from the box into one of the compartments of the spout, such compartment is thereupon closed by the gate, and the other opened to discharge the seed from the latter to the ground. During the subsequent motion of the slide, seed is thrown into that part of the spout which was last opened, but is immediately closed on the insertion of the seed, and the seed from the first compart ment is allowed to pass out. In this manner the gate constitutes a sort of cut-01f, by which the seed-discharge is regulated and controlled. 1% R are thefurrow-openers, pivoted to the front part of the frame A and connected with each other by a cross-bar, p. A crank, s, of this cross-bar is, by a link, it, connected with a bellerank, a, and this, again, by a rod, 11, with a lever, w. 13y moving this last-named lever, the furrow openers can be thrust into the ground, or raised clear of the same, as may be desired. Cutting-disks S are hung in front of the fi1rrow-openers,in ears projecting from the latter, as shown in Figs. 2 and 3. Their position is also regulated, as a matter of course, by means of the lever 10. Under the frame A is also hung a cross-shaft, T, which carries at its ends the check-row markers a and which, by a crank and rod, W, is connected with a lever, 0 (shown in Fig. 2,) and also with a spring, (1 the spring tending to raise the markers out of the ground, while the lever is used to force them in and mark the last hill dropped before turning the -apparatus. For a longitudinal marker, I use a join ted rod, U, which is swiveled at the back of the frame A and carries a marking-plate, 0 as shown. The swivel-joint f of this marker enables it to be thrown to either side, while the joint in the stem of the marker permits the plate 6 to accommodate itself to the soil at either side of the frame A. Y N are a pair of scrapers and brakes, which are attached to a cross-shaft, X, hung on the back part of the frame A, and controlled by a lever, L. These scrapers are used to clean the rim of the wheels B B, and also, if desired, as brakes.

I claim as my invention, and desire to secure by Letters Patent-- 1. The combination of the seed slide I with the levers L M, adjustable pin z, and operating-cam N, all arranged to operate substan tially as herein shown and described.

2. The combination of the cam N, having the spring I in its cam-groove, with the hand-lever O, ratchet-wheel m, pin 2, and levers M 1), as and for the purpose described.
